The Development of Mechanical Gears

Whether studying new forms of gear transmission or new gear machining technologies, it is necessary to master the basic principles of gear meshing. Currently, some methods commonly used in literature related to gear transmission are based on a specific transmission form or tooth profile

To study the special properties of this gear. For example, studying involute gears based on their special properties may result in some conclusions that may not be applicable to other gears. In the face of the various forms of gear transmission and machining methods that have emerged, this research method can no longer meet the needs of production. The development of practice has made it both necessary and possible to study the universal theory of gear meshing. Due to the high degree of generalization and scientific abstraction of this theory, it can more accurately and effectively reflect the essence of gear meshing, discover many laws that are difficult to obtain in the study of individual gear transmissions, and thus promote the research work of various specific gear transmissions more deeply and historically.

In recent years, due to the efforts of a large number of scientific and technological workers at home and abroad, the research on gear meshing principle has developed rapidly and achieved many significant results.

With the rapid development of the machine industry, the application of various new types of gears and gear processing tools is also increasing day by day. In terms of tooth profile shape alone, currently, besides involute, other tooth profiles are also becoming increasingly widely used.
